OK, how many of you have heard that marijuana causes brain damage? Would you like to know the source of this information? Some 22 years ago, two Rhesus monkeys were continuously exposed to doses of marijuana up to 200 times the psychoactive dose for humans.
Researcher Robert Heath observed changes in the brain wave patterns of the monkeys. Even though the brain waves returned to normal within an hour after administration of the drug, Robert Heath predicted that long-term exposure would produce permanent brain damage. Even after numerous studies with equipment far superior to that of Heath's, no other researchers have been able to produce evidence of brain damage. Every man, woman and child in this country is constantly bombarded with the claim that marijuana causes brain damage. -
